Abstract
In this paper the effects of variation of illuminance, spatial frequency and color on measuring accuracy are discussed. The illuminance self-adaption and pixel to pixel AGC function blocks are introduced. By means of the blocks, tolerance of illuminance variation is expanded greatly and several objects with different spatial frequencies or different colors can be measured simultaneously. When optical amplification is 1, the measuring accuracy of the system is 1 micro meter.
